13 Claims. (CL 229-55) This invention relates to a new and improved container and more particularly acollapsible container formed of flexible sheet material which may be shipped and stored flat in knocked down condition.

This container may be made of cardboard or other relatively light weight material and is particularly suited for packaging ice cream or other food products. Inasmuch as these containers are discarded after one use, it is highly desirable that they be of economical construction.

It istherefore an object of the present invention to provide a container which may be quickly asembled at the place where it is to be filled.

It is another object to provide a container which may be shipped and stored in knocked down or flat condition and which may be assembled without the use of adhesives.

It is a further object to provide a container which may be made from light weight material and which may be manufactured at a low cost.

It is another object to provide a container which may be easily assembled without powered machinery.

Another object is to provide a multi-walled container having insulating characteristics.

A further object is to provide a multi-walled container constructed of light weight material which has adequate rigidity and provides extra protection to the contents in that damage to the outer wall will not necessarily affect the inner wall.

Another object is to provide a container in which the top and bottom closures cooperate with the lateral walls to maintain the shape of the container and strengthen the walls.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the specification, drawings and claims appended hereto.

In the drawings which illustrate an embodiment of the invention and wherein like reference char acters are used to designate like parts:

Figure 1 is a plan view on a reduced scale of a blank for forming the side walls of the container.

Figure 2 is a vertical elevation of the container with its top closure separate therefrom.

Figure 3 is a fragmentary sectional view of the container and closure.

Figure 4 is a fragmentary transverse section taken on the line 44 of Figure 3.

Figure 5 is a top plan view of the container closure shown in Figure 2.

container are made from the blank I! shown in Figure 1 The length of the blank is more than twice the circumference of the assembled container. The upper margin of the blank is folded over outwardly to form the rolled edge l4. The lower margin is folded over inwardly to form the rolled edge It, indicated by the broken lines in Figure 1. The width of the blank after the margins are folded is the height of the side walls of the assembled container. The right half of the blank forms the inner wall and the left the outer wall. The outer or left end of the blank has tabs [8 adapted to be inserted in the vertically aligned slots 20 which are at approximately the center of the blank. p

The broken lines 22 indicate creases in the blank which make it possible to easily fold it into a compact flat rectangular shape for purposes of storage and transportation. The tabs l8 may be inserted in the slots 20 after the outer wall has been wrapped around the'inner and the blank may then be folded for storage, thus facilitating ultimate assembly of the container. The slots 20 are in the outer wall of the container eliminating the possibility of the contents leaking through them. In place of these tabs the outer end may be cemented or otherwise secured without the cement coming in contact with the contents of the container and this may be done either at the time of fabrication or assembly. An adhesive may be applied to the blank at the time of fabrication which would merely require that the adhesive be moistened and the outer end secured at the time of assembly; this latter operation may :16 performed while the blank is in folded condi- The container is closed at the bottom by a disk 24 shown in Figure 3. This disk may be made of cardboard or other material which may be of a heavier weight than the side walls. After the outer end of the blank l2 has been secured as by inserting the tabs I 8 in the slots 20, the disk 24 may be inserted by pushing it downwardly until the edge of the under surface is seated on the inner rolled edge IS. The edge of the disk holds the walls outwardly in a cylindrical shape as distinguished from the collapsed and folded condition prior to the insertion of the disk. The rolled edge l6 maybe previously glued or otherwise secured to the walls of the container to insure adequate support for the disk 24. The glued portion being below the disk it does not come in contact with the contents of the container.

The top closure consists of a disk 26 which is Referring to the drawing, the side walls of the ll seated on the rolled edges l4 of the inner and auaooa outer walls and a rim member which consists of a downwardly extending flange 28 which engages the outer rolled edge I4, and a portion 30 projecting above the disk 26 folded back upon itself and terminating in horizontally projecting tabs 32 which engage the upper surface of the disk 26. The rim member may be made from a strip of material of the same type as the side walls. The tabs 32 are formed by notching a margin of the strip and the folding lines are scored. The strip has extended ends 34 which are overlapped and suitably secured together by glue or otherwise fastened forming a ring. The rim may be doubled and flattened for storage purposes and the folds may be made at the time of assembly when the rim is opened up and the tabs 32 turned inwardly and downwardly forming the projecting portion 30 and then, inwardly and horizontally along the second scored line so that the tabs are in a position to overlay the disk 26. To install the cover the disk may be seated on the rolled edges I4 and the rim placed over it or the disk may be inserted in the rim and the rim with the disk then placed on the container with the flanges 28 engaging the rolled edge H.

tainer is filled, this in turn tends to urge the tabs 32 downwardly against the upper surface of the disk 26 to maintain it in place.

The inner rolled edge It tends to maintain the inner and outer walls of the container in spaced relation. Similarly, the lower rolled edge It of the outer wall has the same effect, which results in a certain amount of air space between the walls of the container with its attendant insulating properties. This also gives additional protection to the contents of the container in that damage to the outer wall is less likely to penetrate the inner wall.

It is to be understood that this application is not to be limited by the exact embodiment shown, which is merely by way of illustration and not limitation as various and other forms of the device will, of course, be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
